Embodiment Construction

[0026] based on the following Figure 1 to Figure 10 Embodiments of the flexible printed board of the present invention will be described in detail.

[0027] The flexible printed substrate 11 illustrated here, such as Figure 4 ~ Figure 5 As shown, in the notebook computer A, it is used to electrically connect the film board (substrate to be connected) 42 of the keyboard unit 41 and a main substrate 51 such as a motherboard. In the notebook computer A, the keyboard unit 41 is arranged on the upper side of the main board 51 . In particular, the flexible printed circuit board 11 exemplified in this embodiment electrically connects the connecting portion 45 formed on the rear end of the keyboard unit 41 and the terminal portion 52 formed on the upper surface of the main board 51 .

[0028] like Figure 7 As shown, the keyboard unit 41 has a base plate 44 , a film plate 42 stacked on the upper surface of the base plate 44 , and a so-called key top 43 of a keyboard disposed on t...

Abstract

In a cheap manner, the invention provides a flexible printing substrate and a computer using the flexible printing substrate, wherein the flexible printing substrate takes a connected substrate, which is provided with connected terminals respectively on different surfaces of insulating thin plates, as the connecting object. The flexible printing substrate (11) takes a membrane sheet (42), which possesses connected terminals (45a) on mutually opposite surfaces of each insulating thin plate (42a, 42b), as the connecting object. A connecting terminal (25) respectively connected with the connected terminals (45a) is arranged on a surface of one end of a basement membrane (12) formed by insulators. The basement membrane (12) has a first sheet part (22) and a second sheet part (23) which are mutually adjacent via a gap (21) formed from the edge of one end. Respectively disposed on a surface at the same side, the first sheet part (22) and the second sheet part (23) possess the connecting terminal (25) for connection with the connected terminals (45a) and are folded and overlapped via the gap (21) in such a manner that the connecting terminal (25) is arranged at the outer side and then are bonded.

Description

technical field [0001] The present invention relates to a flexible printed circuit board having a connected substrate having connected terminals on different surfaces of an insulating sheet as a connection object. Background technique [0002] Currently, in a keyboard unit of a notebook computer or the like, a substrate to be connected called a membrane sheet is used. like Figure 11 As shown, the film plate 1 has a double-layer structure having a pair of upper insulating thin plates 2 and lower insulating thin plates 3 facing each other. On the upper side insulating sheet 2 and the lower side insulating sheet 3, wiring is implemented on the surfaces facing each other, and insulation is carried out at necessary places, and when the key is pressed, the contacts facing each other come into contact. [0003] A connection portion for outputting a signal to the outside is formed at an end portion of the thin film plate 1 . The connecting portion is arranged so that the connecte...
